CMake configuration file for ipelet demos processes the "simple_triangulation" example incorrectly

[alekseYY]

Issue Details

It's a minor issue, but anyway. The file demo/CGAL_ipelets/CMakeLists.txt processes a number of ipelets correctly, but in the end it processes the "simple_triangulation" example (which is included in the CGAL Ipelets User Manual) in some different way. As a result, the library libsimple_triangulation.so can't be found by the libCGAL_simple_triangulation.lua loader (cause filenames differ).

The solution I tried and it worked - add the "simple_triangulation" into the list of other ipelets and remove the special treatment of this ipelet:

set(CGAL_IPELETS ${CGAL_IPELETS} simple_triangulation)

Another thing which can be improved - remove complex mechanics to find the IPE directory for ipelets from the demo/CGAL_ipelets/CMakeLists.txt file and use the ~/.ipe/ipelets directory to install ipelets. This will avoid the sudo during installation.
